    这是一个创建于 633 天前的主题，其中的信息可能已经有所发展或是发生改变。

    家里现在是公网 v4 v6 内网设备已经能拿到公网 v6 地址 v6 测试也能通过，但是没法直接在外网通过 v6 访问到内网设备，ddns 的 openwrt 可以正常访问，内网需要怎么设置才能公开？

    防火墙入站放行。tplink 的家用路由就不用试了，默认开启 v6 防火墙且不可调整。

    内网什么设备， 设备自己也有防火墙的，比如 Windows

    默认情况下 wan 是拒绝转发的，你可以改为接受，或者 wan 分离为 wan wan6 然后只对 wan6 转发，也可以自己加 ip6tables 规则

    ”ddns 的 openwrt 可以正常访问“？

    你先解决公网直接访问路由器的问题，然后才是访问路由器后面的设备。

    @hertzry #6 就是 v4 v6 都能访问 openwrt 但是 v6 没法穿透 到设备
    @mcluyu #4 这个检查了没问题，威联通 nas 开了 v6 访问
    @jobmailcn #5 防火墙 wan wan6 是接受转发的，内网通过 v4 转发已经能访问了 现在是准备套 cf 直接访问内网 v6

    OpenWRT 的默认配置，我只需要添加一条 accept `wan` zone 到 `lan` zone 的 forward 就可以了
